Fluid Replacement in Vehicles: Engine Oil & Automatic Transmission Fluid

Engine Oil Change

• Engine oil lubricates components, reducing friction. Change every 8,000–15,000 km or once yearly, depending on usage.

• Coolant is vital for heat dissipation. Replace every 2–3 years or 40,000–60,000 km.

• Brake fluid transmits braking force. Replace every 2 years or 40,000 km.

Automatic Transmission Fluid (ATF)

• Used to lubricate gearbox components.

• Replace every 50,000–100,000 km.

Full vs. Partial ATF Change

• Full change removes all fluid using specialized equipment and includes post-replacement checks.

• Partial change replaces only some fluid via a tube; less thorough than a full change.

Diesel Engines

• Fuel filter: change every 10,000–15,000 km.

• Coolant: same interval—2–3 years or 40,000–60,000 km.

Important:

• Always use fluids specified by the vehicle manufacturer.

• At Hunters Garage, we schedule convenient service times for fluid changes.

• Timely fluid replacement:

  • Extends vehicle life

  • Ensures smooth operation

  • Prevents costly repairs

Note on Polluted Environments

In high-pollution areas like Ukraine, changing engine oil every 8–10,000 km (rather than 15,000 km) is advisable due to:

• Dirt and dust contaminating oil

• Urban stop-and-go reducing oil effectiveness

• Poor fuel quality causing deposits and wear

Fluid maintenance is vital to keep your vehicle in top condition.
